Why are people so uptight ? No one forces you to watch this Kilmer guy or any other 'mechanic' on YouTube (for the record, I've seen maybe 2 of Kilmer's videos). Here's a clue: They aren't doing this for educational purposes anymore. They do this for a living and many of them are living quite comfortably contrary to how they appear "in character".
There is a system when it comes to YouTube. Notice how every single one of them emphasizes subscribing to their channel, liking each video, and how the videos are specific lengths ? YouTube pays based on a tiered system: The more subscribers you have, the more they pay on each watched video. A user "likes" a video ? Cha-ching, more $$$. If you watch a 15-minute video for 2 minutes, it "hurts" their numbers. If they retain a user for "x" minutes, they basically get full credit.
Do you folks watch TV shows that you think are stupid and don't like ? Bet you don't - you turn the channel. When a song comes on the radio that you don't like, do you listen to it ? I'm sure you don't. Don't like Kilmer, South Main Auto, Eric the Car Guy ? Move along....
